SAFETY ATTACHMENT FOR CARS.

SPECIFICATION forming part of Letters Patent No. 488,477, dated December20, 1892.

Application filed September 13, 1892. Serial No. 445,799. (No model.)

To all whom, t may con/cern.:

Be it known that I, ROBERT L. LYNCH, a citizen of the United States,residing at Leeport, in the county of Trimble and State of Kentucky,have invented a new and useful Safety Attachment for Oars, of which thefollowing is a specification.

My invention relates to a safety attachment for railway cars, the objectot' the invention being to provide means to prevent derailment of carswhile in motion, and thereby prevent accidents due to such causes.

The invention is fully described hereinafter in connection with thedrawings and the novel features thereof are particularly pointed out inthe appended claims.

In the drawings: Figure l is a side view of a truck showing theattachment applied thereto; Fig` 2 is a transverse sectional view of thesame; Fig. 3 is a derail view of the attachment.

A represents an ordinary car-truck, above the boxes, B, of which isarranged the longitudinal timber, O, and beneath the truck, andextending parallel with said timber, isahorizontal supporting-bar, D,having terminal, outward extending arms, E E, which extend under theboxes and are tlrinly secured to the same by vertical bolts, F F.Similar bolts, F, extend vertically through the supporting-bar andtimber, above-described. Said outward extending arms are bifurcated asshown, their upper leaves being hinged at their inner edges to thesupporting-bar.

G represents a yoke, arranged beneath the supporting-bar, and providedwith shoulders, g g which bear against the under surface thereof, thearms of said yoke being extended to form screw-threaded stems, H I-I,which extend vertically through the supporting-bar Aand are engagedabove the same by taps, h h.

Smooth stems may be employed, if preferred, and held in place bytransverse pins, of any ordinary or approved construction. Interposedbetween the nuts and the upper surface of the supporting-bar, is acap-plate, K,

and between the latter and the upper surface displacement.

of the bar is a tension spring, M, which allows a limited vertical playof the yoke, for a purpose hereinafter explained. Mounted upon the yoke,at its lower end, is a safety roller, N, which runs upon the undersideof the flange, O, of the rail, P, and prevents the truck from rising. Itis in the nature of an anti-friction traveler, held in such a positionas to engage the track when the truck rises, and thereby preventderailment.

The spring, above described, allows` a limited play of the parts toprevent fracture or The bifurcated arms enable the position of the rollto be adj usted, by blocking between the leaves before tightening thebolts. Oil holes, Q, communicate with the bearings of the safetyrollers.

Having thus described my invention what I claim and desire to secure byLetters Patent is:-

l. An attachment for car-trucks, comprising a fixed supporting-bar, avertically movable yoke whose arms extend through said supporting-bar, acap-plate K connecting said arms above the supporting-bar and held inplace thereon by adjusting-nuts, a pressurespring located between thecap-plate and the supporting-bar, and a roller carried by the yoke,substantially as specified.

2. In asafety attachment for car-trucks, the combination of thesupporting-bar provided with parallel, bifurcated arms, adapted to bebolted to the undersldes of the boxes of the truck, the verticallymovable yoke provided with stems extending through the supportingbar andtted with a tension spring, and a roller mounted upon the yoke to engagea horizontal flange upon the track-rail, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
